The Seattle Sounders opponents in Tuesday night’s U.S. Open Cup second round match at Starfire Sports Entertainment Complex on Tuesday night, the Portland Timbers, arrived in Seattle on Monday to prepare for one of the most intriguing clashes in the history of the Sounders Timbers I-5 rivalry.

The Sounders finished training on Monday practicing spot kicks ahead of the winner take all match. The team will have to manage again without the services of their captain Danny Jackson, who is in England finishing his application for his green card, but it looks as though Leighton O’Brien has returned to full fitness and will figure in the match.

Seattle is desperate to improve after their disappointing performance in Saturday night’s regular season match against the Montreal Impact at Qwest Field. Portland, who is off to a great start in their regular season schedule, is looking to avenge a loss and a draw to the Sounders early in the year.

The winner of the match will host Chivas USA of Major League Soccer in the third round of the tournament.
